25
Hyperkalaemia mx
30ml 10% Ca gluconate 10 U actrapid in 50ml 50% glucose
26
Pattern in resp acisodis
low pH High CO2
27
Pattern in rep alk
High pH Low CO2
28
Pattern in met acid
Low pH Low bicarb
29
Patern in met alk
High pH High bicarb
30
BE more neg than -2=
met acidosis
31
BE more positive than +2 =
met alk
32
Chest compressions
- 5-6cm - 100-200 comp per min
33
precordial thump?
only when it can be used without delay whilst aw defib in VT/VF
34
laryngectomy and tracheal stoma
give oxygen and if required assist ventilation via stoma
35
inital naloxone doses
400 mcg IV 800 mcg IM 800mg SC
36
anaphylaxis adrenaline dose
500 mcg IM (1:1000)
37
Preganancy
L lateral position manualy displace uterus to L L lateral tilt if faesable
38
adrenaline has both
alpha adrenergic and beta adrenergic effects
39
consider bicarb use when
- Hyperk - TCA overdose - 50ml of 8.4% solution
40
bicarb effects
- Exacerbates intracellular acidosis - Negative inotropic effect on myocardium - shift L of O2 curve
